[Effects of Invention]

According to the present invention, it is possible to provide an electric vacuum cleaner that can select the storage method during charging according to the use state of the electric vacuum cleaner.

Hereinafter, the mode for implementing the present invention (hereinafter referred to as "embodiment") will be described in detail with reference to appropriate drawings.

Fig. 1(a) is a perspective view showing a state in which the electric vacuum cleaner of this embodiment is stored in an upright state on a charging stand.

The electric vacuum cleaner 100 can be changed to various usage states such as a hand-held state and an upright state for cleaning. The charging stand 70 a that houses the electric vacuum cleaner 100 houses the electric vacuum cleaner 100 in an upright state, and is configured to include a base member 71, a stand member 72 and a holder member 73. To the holder member 73, the output plug 81 of the AC converter 80 is mounted to charge the battery 3 assembled in the electric vacuum cleaner 100. When the electric vacuum cleaner 100 is installed on the charging stand 70a, the output plug 81 is connected to the electric vacuum cleaner 100 The input socket 17b can be charged. In this way, it can be configured that it is not necessary to install any electric components in the charging stand itself, and it is possible to suppress costs and improve productivity. In addition, since the presence or absence of the frame member 72 does not affect the electrical connection, the reliability of the product can be ensured.

The base member 71 has a mounting surface 71a and an extension 71b. The mounting surface 71a is a part of a substantially rectangular plate shape. The extension 71b is a portion having a substantially truncated cone shape. The extension 71b is provided so as to be substantially perpendicular to the placement surface 71a. The central axis of the extension 71b is set to be positioned approximately at the center of the placement surface 71a in the short-side direction and approximately 3/4 of the long-side direction.

Moreover, FIG. 1(b) is a perspective view which shows the state which accommodated the electric vacuum cleaner of this embodiment in a hand-held state in a charging stand. The charging stand 70b in this state stores the electric vacuum cleaner 100 in a hand-held state, and is different from the charging stand 70a in that the stand member 72 is omitted and only the base member 71 and the holder member 73 are provided.

Figure 2 is an exploded view of the electric vacuum cleaner of this embodiment.

As shown in FIG. 2, the electric vacuum cleaner 100 is configured to include: a cleaner body 1; a dust box 2 (dust collecting device); a battery 3 (power storage device); and an airtight maintaining member 90.

The cleaner body 1 is configured to include a body portion 10, a motor box portion 11, and a handle portion 12.

The main body 10 is formed with a connection port 10a (suction port) such as an extension tube 300 (refer to FIG. 1) or a standard suction port 400 (refer to FIG. 1). The connection port 10a is molded from the same resin as the main body 10, the motor box 11, the handle 12, and the like. In addition, the connection port 10a has a substantially circular opening and is formed toward the front. In addition, to the connection port 10a, a gap/brush replacement nozzle 110, an extension pipe 300, a standard suction port 400, a small suction port 600, a broom-type suction port 700, etc., which are accessories, are connected (hereinafter sometimes collectively referred to as accessories).

Moreover, the dust box 2 is detachably assembled in the main body 10, and an introduction pipe 14 is provided for sending air containing dust sucked from the connection port 10a into the dust box 2 (refer to FIG. 3).

The motor box portion 11 contains an electric blower 40 (refer to FIG. 6) and a main body substrate 50 (refer to FIG. 6). In addition, in the front of the motor box portion 11, a circular suction port 11a for sucking in clean air after dust collection using the dust collecting box 2 is formed. In addition, on the front surface of the motor box portion 11, a body terminal portion 17 connected to the charging stand 70 is provided at a lower portion than the suction port 11a.

The handle portion 12 is provided on the rear side of the main body portion 10, and has a gripping portion 12a formed in a substantially L-shape. This gripping portion 12a has a first gripping portion 12a1 extending linearly in the front-rear direction, and a second gripping portion 12a2 extending linearly in the substantially vertical direction. The first grasping portion 12a1 is located on the upper side and the front side than the second grasping portion 12a2. The second gripping portion 12a2 is slightly inclined with respect to the up-down direction so that the upper portion faces forward. Moreover, the 1st grasping part 12a1 and the 2nd grasping part 12a2 are substantially rod-shaped, and are formed continuously. As described above, the first grasping portion 12a1 and the second grasping portion 12a2 are formed in a linear shape, so that the user can easily recognize the position of the hand. In addition, since the first grasping portion 12a1 and the second grasping portion 12a2 are bent and connected at an angle approaching a right angle, when grasping the first grasping portion 12a1, the hand is not easy to slip away from the second grasping portion 12a2, and When grasping the second grasping portion 12a2, the hand is not easy to slip away from the first grasping portion 12a1.

In addition, the handle 12 is provided with a locking member 13 for locking the battery 3. This locking member 13 is formed in a button type, and is swayably supported.

In addition, an operation button 12b is provided on the upper surface of the first grasping portion 12a1 of the handle portion 12. The operation button 12b is composed of, for example, three buttons of "strong", "standard", and "off".

On the upper part of the front end of the main body 10, there is provided a release button 18 which is operated when accessories such as the extension pipe 300 (refer to FIG. 1) are removed. By pressing this release button 18, the lock between the main body 10 and the accessory can be released, and the accessory can be detached from the main body 10.

In addition, an airtight keeping member 90 is attached to the front end of the main body 10. This airtight holding member 90 has a cylindrical body 91 having a substantially circular shape. This cylinder 91 has an elastic portion 91a formed in a ring shape with soft resin on the front end side. The cylinder 91 has a base end side formed of a material harder than the aforementioned elastic portion 91a, and is connectable to the connecting portion 91b of the main body portion 10. The cylinder 91 is formed by integrally molding two different types of members of the elastic portion 91a and the connecting portion 91b. Furthermore, the elastic portion 91a is composed of an elastically deformable (bendable) material such as an elastic body. By attaching such an airtight holding member 90 to the connection port 10a of the cleaner body 1, the entire front end 90s of the airtight holding member 90 can be tightly attached to the ground, and the attractive force can be improved compared to the case of not being tightly attached. In addition, by forming the connecting portion 91b with a hard material, the airtight holding member 90 can be attached to the main body 10 in a stable state without falling off.

In addition, in this embodiment, the case where the elastic portion 91a is formed of an elastic material such as an elastic body is described as an example, but it is not limited to this. For example, it is possible to form substantially the entire cylindrical body 91 with the same material as the connecting portion 91b, and to equip the front end of the cylindrical body 91 with short hairs that have been electrostatically implanted in a ring shape. Those equipped with this kind of electrostatic flocking can also make the front end of the airtight holding member 90 tightly contact the ground, like the elastic body, and can increase the attractive force.

On the outer side surface of the connection port 10a of the main body 10, an elongated fitting groove 10b is formed in the longitudinal direction. This fitting groove 10b is formed on each of the left and right sides. At the base end of the connecting portion 91b, there is formed a projection (not shown) that engages with the aforementioned fitting groove 10b by unevenly fitting and locking.

In addition, the main body 10 is provided with a light emitting element 10c (refer to FIG. 2) above the connection port 10a. This light-emitting element 10c is configured to emit light toward the front, that is, the surface to be cleaned (ground surface, etc.). In addition, the front end surface 10c1 of the light emitting element 10c is positioned on the same surface as the front end 10a1 of the connection port 10a.

The storage battery 3 supplies electric power to the electric blower 40 (refer to FIG. 6) and the like, and is composed of a secondary battery such as lithium ion and nickel hydride. In addition, the storage battery 3 has a substantially semi-cylindrical box body 3a made of synthetic resin, and can be attached to and detached from the main body 10 by sliding the box body 3a in the front-rear direction.

On the upper surface of the box body 3a, a terminal portion 3b connected to the main body portion 10 is provided. In addition, on the upper surface of the box body 3a, in front of the terminal portion 3b, a sliding groove 3c that is slidably supported with respect to the main body portion 10 is formed. In addition, on the upper surface of the box body 3a, behind the terminal portion 3b, slide rails 3d and 3d that are slidably supported with respect to the main body portion 10 are formed so as to protrude toward the left and right sides.

In addition, on the front surface of the box 3a, an introduction hole 3e for introducing cooling air for cooling the battery 3 is formed on one side (left side) in the left-right direction (width direction). This introduction hole 3e is formed to extend elongated in the up-down direction.

In addition, on the front surface of the box 3a, on the other side (right side) in the left-right direction (width direction), a discharge hole 3f for discharging air after cooling the battery 3 is formed. This discharge hole 3f is formed to have a bilaterally symmetrical shape with the aforementioned introduction hole 3e.

In addition, on the back of the box 3a, a locking recess 3g into which the locking member 13 is fitted and locked to the main body 10 is formed.

Fig. 3 is a view of the arrow in the X direction of Fig. 2.

As shown in FIG. 3, the dust collecting box 2 adopts a cyclone method, and has the function of separating the dust-containing air sucked from the inlet pipe 14 into dust and air, and then collecting the dust. In addition, the dust box 2 is arranged in front of the motor box portion 11 with the axial direction as the front-rear direction, and has a storage portion 2a having a substantially cylindrical shape. In addition, on the upper surface (side surface) of the dust box 2, a substantially rectangular inflow port 2b connected to the introduction pipe 14 is formed (refer to FIG. 2). The air containing the dust that flows into this inlet 2b will become a vortex, and centrifugal force is applied to the dust. After the dust is separated into dust and air in the dust box 2, the air that has separated the dust will flow from the back of the dust box 2 (back )discharge.

In addition, in front of the dust box 2, a cover 2c that must be opened and closed when the dust accumulated in the dust box 2 is discarded is rotatably supported via a pivot portion 2d. In addition, a lid lock mechanism 2e for unlocking the lid 2c is provided on the upper portion of the lid 2c. Furthermore, the internal mechanism of the dust box 2 is constructed based on Japanese Patent Application Laid-Open No. 2016-137165.

In the lower part of the motor box portion 11, an exhaust port 16 is provided. This exhaust port 16 has a plurality of slits 16a along the front-rear direction, and the plurality of slits 16a are formed to be aligned in the up-down direction. Furthermore, although not shown, the exhaust ports 16 are provided on the left and right sides.

Fig. 4 is a perspective view of the electric vacuum cleaner of this embodiment.

As shown in FIG. 4, in the electric vacuum cleaner 100, the dust box 2 is installed under the main body 10 and in front of the motor box 11. At this time, if the dust box 2 is installed in the cleaner body 1, the lid lock mechanism 2e is hidden on the cleaner body 1 side. The reason is that when the lid lock mechanism 2e is installed on the opposite side (outer side), the lid lock mechanism 2e may be released during cleaning, but by hiding the lid lock mechanism 2e on the side of the cleaner body 1, erroneous operation can be prevented. For example, when cleaning the underside of a sofa or a bed in an upright state, etc., the vacuum cleaner main body 1 may be brought close to the ground horizontally. At this time, when the lid lock mechanism 2e is installed on the front side, it may come into contact with the ground and the lid lock mechanism 2e may be released. The positions of the lid lock mechanism 2e and the pivot portion 2d are not limited to these, and may be provided on the left and right sides of the cleaner body 1.

In addition, the dust box 2 is detachably provided with a maintenance brush 2s (refer to Figs. 2 and 3). The maintenance brush 2s is arranged at a position where the dust box 2 is hard to see from the outside when the dust box 2 is installed in the cleaner body 1. Therefore, it is not easy to fall off during operation, and there is no need to store the maintenance brush 2s in a place other than the electric vacuum cleaner 100.

In addition, when the airtight holding member 90 is attached to the cleaner body 1, the airtight holding member 90 covers the light-emitting element 10c. In other words, the inner diameter of the airtight holding member 90 is set so that the light-emitting element 10c is positioned more inside than the airtight holding member 9.

Figure 5 is a plan view of the electric vacuum cleaner of this embodiment.

As shown in FIG. 5, the connection part 91b of the airtight maintenance member 90 is formed with extension parts 91b1, 91b1 extended toward the back on both left and right sides. A recessed portion 91b2 is formed between the extended portion 91b1 on the left and the extended portion 91b1 on the right in a plan view. This concave portion 91b2 is fitted with the front end 10d1 of the protrusion 10d formed on the upper surface of the front end of the main body portion 10. Thereby, the airtight holding member 90 is aligned in the front-rear direction and the left-right direction with respect to the connection port 10a (refer to FIG. 2).

The introduction pipe 14 formed in the main body 10 is formed to extend diagonally to the right and then downward, and is connected to the inlet 2b (refer to FIG. 2) of the dust box 2. Thereby, a vortex can be generated in the accommodating portion 2a of the dust box 2, and the dust can be separated efficiently by centrifugal force.

The width of each of the dust box 2 and the storage battery 3 is formed to be slightly shorter than the width W of the main body 10. In other words, it is configured such that the dust box 2 or the storage battery 3 does not protrude from the side of the main body 10. In this way, regardless of whether the user uses the left hand or the right hand to grasp for cleaning, the electric vacuum cleaner 100 can be smoothly moved in the front and rear directions, which is easier to use.

Fig. 6 is a sectional view taken along the line VI-VI in Fig. 5. Furthermore, FIG. 6 is a state where the airtight holding member 90 is removed from the electric vacuum cleaner 100. As shown in FIG.

As shown in FIG. 6, in the motor box portion 11 of the main body portion 10, an electric blower 40 is housed. In addition, in the motor box portion 11, below the electric blower 40, a main body board 50 (control board) for controlling the cleaner body 1 is housed.

The electric blower 40 is horizontally arranged so that the rotating drive shaft 40a faces the front-rear direction. In addition, the air discharged from the electric blower 40 flows to the main body substrate 50 arranged below the electric blower 40 to cool the main body substrate 50. In addition, a part of the air cooling the main body substrate 50 cools the battery 3.

The main body substrate 50 has an upper substrate 50a and a lower substrate 50b which are divided into upper and lower and arranged in two stages, and various components are mainly mounted on opposing surfaces (the lower surface of the upper substrate 50a and the upper surface of the lower substrate 50b). Most of the air discharged from the electric blower 40 flows and cools the components (heat-generating components) arranged facing each other on the main body substrate 50. In addition, the main body substrate 50 is covered by a flame-retardant resin box 51, and the wind (air) discharged from the electric blower 40 flows from the rear side to the front side through the resin box 51, and then passes under the bottom surface of the resin box 51 to flow. Go to the battery 3 side.

In addition, the electric blower 40 and the main body substrate 50 are arranged to overlap in the vertical direction. Therefore, the size in the front-rear direction can be shortened. In addition, the electric blower 40 is formed by expanding the motor box portion 11 toward the handle portion 12 side, so that the size of the main body portion 10 in the front-rear direction (full length) can be shortened.

In addition, the electric blower 40 and the main body substrate 50 are located below the first gripping portion 12a1 of the handle portion 12. Thereby, when the user grips and operates the gripping portion 12a1, the center of gravity of the electric vacuum cleaner 100 will be near below the first gripping portion 12a1. Therefore, the electric vacuum cleaner 100 can be held stably when the front end of the electric vacuum cleaner 100 is used upward.

In addition, between the first gripping portion 12a1 and the upper surface 11c of the motor box portion 11, a gap 12c of a width H1 for inserting a hand is formed. Furthermore, between the second gripping portion 12a2 and the back surface 11d of the motor box portion 11, a gap 12d of a width H2 that is wider than the width H1 is formed. As described above, when cleaning by grasping the first grasping portion 12a1, the arm can be maintained in an extended state. Therefore, the electric vacuum cleaner 100 can be moved back and forth without having to grasp the first grasping portion 12a1. In addition, when cleaning by grasping the second grasping portion 12a2, it is necessary to insert the hand (finger) greatly toward the gap 12d and grasp it tightly. Therefore, by making the width dimension H2 wider than the width dimension H1, it is possible to stably grasp the second Grip 12a2.

In addition, the thickness T1 of the first grasping portion 12a1 is formed to be thin, and the thickness T2 of the second grasping portion 12a2 is formed to be thicker than the thickness T1. That is, the first grasping portion 12a1 is formed thinly, and the second grasping portion 12a2 is formed thicker. As described above, when the second gripping portion 12a2 is gripped for cleaning, by increasing the thickness T2 of the second gripping portion 12a2, it is not only easy to grip deeply, but also can increase the strength of the second gripping portion 12a2.

The storage battery 3 is composed of, for example, a lithium ion battery with high energy efficiency. In addition, the battery 3 is arranged below the second grasping portion 12a2 of the handle portion 12. As mentioned above, by arranging the battery 3 at the rear end of the electric vacuum cleaner 100, the center of gravity of the handle portion 12 will be closer to the second gripping portion 12a2, so when the front end of the electric vacuum cleaner 100 is used upwards, it can be easier to operate .

As for the locking member 13, a button-type operation portion 13a is formed at the rear end portion. This operation portion 13a has an arm portion 13b extending along the front, and the front end of the arm portion 13b is supported by the main body portion 10. In addition, the arm portion 13b is urged downward by the spring 13c. Thereby, when the locking member 13 is fitted into the locking recess 3g and locked, the operation portion 13a does not fall off from the locking recess 3g. In addition, when the battery 3 is detached from the main body 10, the operating portion 13a is pressed to be biased by the spring 13 and rebound, and the operating portion 13a can be detached from the locking recess 3g.

As described above, by providing the storage battery 3 as a removable type, the replacement of the storage battery 3 can be made easier compared to those that cannot be removable. In addition, by selectively preparing the reserve battery 3 and the charging box that can charge the reserve battery 3, when the battery on the main body side of the electric vacuum cleaner 100 is exhausted, it is replaced with the reserve battery 3, thereby prolonging cleaning time. With such a configuration, it can be useful when cleaning a wide floor such as a shop.

As shown in FIG. 6, when the front end surface passing through the connection port 10a of the main body 10 is referred to as R1, the front end 2f of the dust box 2 and the surface R1 (a surface extending in the vertical direction relative to the paper surface) are substantially the same plane. Furthermore, the front end 2f of the dust box 2 becomes less protruding forward than the surface R1. Thereby, even when cleaning is performed in a state where the airtight maintaining member 90 is not attached to the cleaner body 1, the front end of the connection port 10a can be brought into contact with a hard ground such as the floor while cleaning.

In the dust box 2, the filter sheet 5 is accommodated in the axial direction rear end of the accommodation part 2a. The filter sheet 5 is configured to be folded into a corrugated shape, which can increase the area of the filter sheet and reduce the pressure loss caused by the filter sheet 5 at the same time.

In addition, the filter 5 is composed of, for example, a high-density HEPA filter (High Efficiency Particulate Air Filter). HEPA filter refers to an air filter that has a particle collection rate of 99.97% or more for particles with a particle size of 0.3 μm at a rated air volume, and has the performance of an initial pressure loss of 245 Pa or less.

Figures 7(a)(b) and 9(a)(b) are perspective views of the charging stand 70a and the charging stand 70b in the state of the electric vacuum cleaner 100 in this embodiment, and Figs. 8 and 10 are respective exploded views . The connecting portion of the base member 71 and the stand member 72 and the connecting portion of the stand member 72 and the holder member 73 have the same shape, and are configured to be changeable. In other words, the shape of the base protrusion 71c of the base member 71 and the protrusion 72b of the stand member 72 are the same shape, and the concave section 72h of the stand member 72 and the holder member 72 have the same shape. The shape of the concave portion 73h of 73 is the same shape.

The base member 71 has a mounting surface 71a on which the standard suction port 400 (refer to FIG. 1) is mounted and which is substantially rectangular. In addition, the base member 71 has an extended portion 71b extending upward at approximately the center in the width direction (left-right direction) and approximately 3/4 of the longitudinal direction (front-rear direction). At the front end of this extension portion 71b, a base projection shape portion 71c capable of selectively mounting the stand member 72 or the holder member 73 is provided. In addition, the base member 71 is provided with a counterweight 75 (not shown) inside, and when the electric vacuum cleaner 100 is installed on the charging stand 70, the charging stand 70 does not easily fall down.

The stand member 72 has a substantially cylindrical shape, and the lower end portion becomes a concave portion 72h that fits with the base protrusion shape 71c of the base member 71. In addition, a stand projection shape portion 72b to which the holder member 73 can be attached is provided at the upper end, and its shape is the same as that of the base projection shape portion 71c provided at the upper end of the base member 71.

By connecting the frame member 72, the fixture member 73, and the base member 71 constructed in this way to connect, as shown in FIG. 7, the base member 71, the frame member 72, and the fixture member 73 form a continuous surface to obtain A charging station 70 with a good appearance.

In addition, by coupling and connecting the holder member 73 and the base member 71, as shown in FIG. 9, the holder member 73 and the base member 71 become a continuous surface, and a charging stand with a good appearance can be obtained.

In other words, the charging stand 70a or the charging stand 70b is a person who can attach and detach the AC converter 80 for charging the battery 3 of the vacuum cleaner body 1, and can be installed and removed from the base member 71, the stand member 72 and the fixing The combination of the device member 73 and the combination of the base member 71 and the holder member 73 like the charging stand 70b are selected and used. At this time, an electric vacuum cleaner can be provided. Whether the electric vacuum cleaner 100 is mainly used in a hand-held state or in an upright state, the storage method for charging can be selected according to the state of use of the electric vacuum cleaner 100.

Furthermore, the stand member 72 is configured to be divided into a plurality of members. In this case, an electric vacuum cleaner can be provided, which has a charging station that can select a preferred height.

Furthermore, the holder member 73 is provided with a hole that can be fixed to the wall surface with screws or the like.

11(a)(b) is an enlarged view of the mounting portion of the output plug 81 of the AC converter 80 of the holder member 73. FIG. The upper surface 73b of the holder member 73 is provided with an opening 73i in which the output plug 81 of the AC converter 80 can be mounted, and by mounting the output plug 81 here, it can be used as a charging stand for charging the electric vacuum cleaner 100. The output plug 81 is installed so as to protrude upward from the upper surface 73b of the holder member 73, and has a substantially rectangular parallelepiped guide portion 73a on its left and right sides as a guide when the main body is installed. This guide portion 73a is adopted to make it difficult to apply a load to the output plug 81. This guide portion 73a is formed with a chamfered portion at the front end.

In addition, on the front surface 73d of the holder member 73, a guide portion 73e having a substantially rib-like shape is formed. This guide portion 73e is a member that can guide the cleaner body 1 (refer to FIG. 2) to the output plug 813 while preventing the cleaner body 1 from collapsing, and is formed to protrude forward from both end edges of the front surface 73d. Moreover, the protrusion 73f is provided in the lower part, and it is formed so that by fitting with the bottom part of the dust box 2 attached to the cleaner body 1, the cleaner body 1 is further prevented from collapsing.

Fig. 12 is a perspective view of a state where the main body terminal portion of the electric vacuum cleaner connected to the output plug 81 of the AC converter 80 is looked up from the dust box side.

As shown in FIG. 12, the main body terminal portion 17 of the cleaner main body 1 is formed with a fitting recess 17a into which the guide portion 73a (refer to FIG. 20) of the charging stand 70 fits. At the center in the fitting recess 17a, an input socket 17b connected to the output plug 81 of the AC converter 80 is arranged. The input socket 17b is connected by a terminal (not shown) connected to the terminal portion 3b of the battery 3 and a lead wire (not shown).

FIG. 13 is an external view of the AC converter 80. Furthermore, this embodiment uses a type that connects a direct AC converter to a socket, and a type that connects to the socket via a socket-attached cable can be used from the main body of the AC converter 80.

Fig. 14 is an external view showing a state where the AC converter 80 is directly connected to the electric vacuum cleaner to be charged. With such a structure, even if there is no space for placing the charging stand, the space can be saved for charging.

Fig. 15(a) is a perspective view showing how the AC converter 80 is attached to the holder member of the charging stand, and Fig. 15(b)(c)(d) is a central sectional view.

The user lowers the cleaner body 1 from above the output plug 81 by turning the cleaner body 1 downward, and connects the body terminal portion 17 to the output plug 81. At this time, since the output plug 81 is formed to face upward, the main body terminal portion 17 can be reliably connected to the output plug 81 by the weight of the electric vacuum cleaner 100.

16 is a cross-sectional view showing the connection state between the main body terminal portion and the output plug 81. When the guide portion 73a of the charging stand 70 is fitted into the fitting recess 17a of the main body, the output plug 81 and the input socket 17b located in the center will be fitted, and the AC converter 80 and the vacuum cleaner 1 are electrically connected. While the cleaner body 1 is installed in the charging station 70, the output plug 81 and the input socket 17b will maintain a contact state, and the battery 3 will continue to be charged.

Furthermore, since the output plug 81 is recessed and convexly fitted with the body terminal portion 17, for example, even if the user touches the cleaner body 1 during charging, the conduction state (contact state) between the body terminal 17d and the terminal 73c is not released.

In the charging stand 70 configured in this way, the output plug 81 is formed on the upper surface 72b of the stand member 72. Therefore, when the output plug 81 is installed at the terminal portion 17 of the body, it is close to the user's line of sight, so it is easy to connect the output plug 81 By inserting into the body terminal portion 17, the cleaner body 1 can be easily installed on the charging stand 70.

In addition, in the charging stand 70, the output plug 81 is formed on the upper surface 72b of the stand member 72. That is to say, the output plug 81 is formed at a position higher than the ground, so that debris is not easy to accumulate on the output plug 81, and it is also possible to reduce the dust rising from the ground and adhering.

In addition, in the electric vacuum cleaner 100 installed on the charging stand 70, the output plug 81 is located near the center of gravity of the electric vacuum cleaner 100 (the position of the electric blower 40 and the battery 3). Therefore, the output plug 81 receives the position near the center of gravity. The vacuum cleaner body 1 can be stably held on the charging stand 70 during charging.

In addition, by installing the electric vacuum cleaner 100 on the charging stand 70, it can be charged with the dust box 2 removed, so that it can be charged even when the dust box 2 is washed and dried.

In addition, a configuration is adopted in which the output plug 81 faces upward and the body terminal portion 17 is connected to the output plug 81 from above. Thereby, since the weight of the electric vacuum cleaner 100 can be mainly applied to the output plug 81, the main body terminal portion 17 and the output plug 81 can be reliably connected.

On the back of the stand member 72 and the holder member 73, grooves 72g and 73g in which the output cable 82 of the AC converter 80 can be arranged are provided.

In addition, although not shown, the charging stand 70 can be stored and charged with the standard suction port 400 or other accessories connected to the electric vacuum cleaner 100.

Furthermore, the charging stand 70 can also be used as a stand for storing the electric vacuum cleaner 100 when the AC converter 80 is not connected and the battery 3 is not charged.

In addition, when the electric vacuum cleaner 100 is stored in the charging stand 70, the battery 3 is located at the upper end, and the locking member 13 is located at the upper end of the battery 3, thereby making it easier to attach and detach the battery 3.

In other words, in a vacuum cleaner storage stand that can store a vacuum cleaner, the vacuum cleaner storage stand has a base member 71; a stand member 72; and a holder member 73. Only the vacuum cleaner storage stand in a state where the base member 71 and the holder member 73 are connected can store the first The vacuum cleaner in the first state (hand-held state), and the vacuum cleaner storage table in the state where the base member 71, the stand member 72 and the holder member 73 are connected is a vacuum cleaner storage table that can store the vacuum cleaner in the second state (upright state). It has the effect of providing an electric vacuum cleaner which can select the storage method at the time of storage according to the use state of the electric vacuum cleaner 100.

Fig. 17 is a view of the usage form when the electric vacuum cleaner is in an upright state when cleaning the floor.

Fig. 17 shows the extension pipe 300 and the standard suction port 400 connected to the electric vacuum cleaner 100 (maintaining the state where the airtight holding member 90 is installed) to be in an upright state, and the electric vacuum cleaner 100 is protruded forward than the user to clean the floor Happening. In this case, the user can grasp the second grasping portion 12a2 of the handle portion 12, and at the same time can move the electric vacuum cleaner 100 back and forth for cleaning. Also, although not shown, when cleaning the floor with the electric vacuum cleaner 100 positioned on the left and right sides of the user, the user can grasp the first gripping portion 12a1 of the handle portion 12, and simultaneously make the electric vacuum cleaner 100 front and rear mobile. As described above, when the user cleans the floor, the position of the handle 12 can be changed to clean.

Fig. 18 is a view of the usage pattern of the electric vacuum cleaner in an upright state when cleaning high places.

In addition, when adjusting to an upright position, the electric vacuum cleaner with the center of gravity on the front side (refer to Japanese Patent Application Publication No. 2016-137165), the user must lift the electric vacuum cleaner upward when cleaning the electric vacuum cleaner in a place higher than the ground The front end is easy to bear the burden on the wrist.

Therefore, in this embodiment, as shown in FIG. 18, the weight of the electric vacuum cleaner 100, namely, the electric blower 40 (refer to FIG. 6) or the battery 3 is located near the handle 12 (close to hand), so the electric The center of gravity G of the vacuum cleaner 100 will become closer to the user's hand. In this way, the electric vacuum cleaner 100 is adjusted to an upright state, and even if the electric vacuum cleaner 100 is used to clean a place higher than the ground, the cleaning can be made easier and easier to use. In FIG. 18, although the case of cleaning stairs is described as an example, it is effective when the electric vacuum cleaner 100 is picked up to clean the panel of an indoor unit of an air conditioner.
